" On Wednesday, he will lay out his aspiration for a thinner, simpler contract. A school site its teachers and administrators should have latitude to choose from a broad menu of options or even come up with their own, and then be held accountable for the results, JoanSullivan, deputy mayor for education, said in elaborating on the mayor's plans.

A method for fixing a bone block in a bone tunnel comprising the steps of placing the bone block in the bone tunnel, advancing spaced-apart first and second metal wires through the bone, transversely of the bone tunnel, so as to intersect the bone block and extend through the bone block, removing one of the wires and replacing the one removed wire with a first absorbable rod, and removing the other of the wires and replacing the other removed wire with a second absorbable rod, whereby to retain the bone block in the bone tunnel with the absorbable rods.

Claim:

What is claimed is: 1. A method for fixing a bone block in a bone tunnel in a bone, said method comprising the steps of: placing a solid bone block in the bone tunnel; advancing at least one trocar and trocar sleeve assembly into the bone transversely of the bone tunnel such that a distal end of said at least one trocar and trocar sleeve assembly resides in said bone proximate the a sidewall of said bone tunnel, the trocar in said at least one assembly being disposed within and substantially filling its associated trocar sleeve; removing said trocar from said at least one trocar and trocar sleeve assembly and inserting a rod into said at least one sleeve; slidably inserting one end of an elongate shaft into said sleeve so as to abut said rod; tapping the other end of said elongate shaft so as to drive said rod out of said sleeve, through said bone and into said bone block. 2. The method of claim 1 wherein a piece of tissue is fixed in said bone tunnel instead of a bone block. 3. The method of claim 1 wherein said rod penetrates through said bone block. 4.

A method of replacing an ACL with a graft. The method provides for the drilling bone tunnels in a femur and a tibia. A replacement graft is provided having first and second ends. A biodegradable composite screw is provided. The screw is made from a biodegradable polymer and a bioceramic or a bioglass. At least one end of the graft is secured in a bone tunnel using the biodegradable composite screw.

A method for fixing a portion of a piece of tissue in a bone tunnel comprising the steps of placing the portion of a piece of tissue in the bone tunnel, advancing spaced-apart first and second metal wires though the bone, transversely of the bone tunnel, so as to intersect the bone tunnel and extend into the portion of a piece of tissue, removing one of the wires and replacing the one removed wire with a first rod, and removing the other of the wires and replacing the other removed wire with a second rod, whereby to retain the portion of a piece of tissue in the bone tunnel with the rods.

Claim:

What is claimed is: 1. A rack assembly for cross-pinning a portion of a piece of tissue in a bone tunnel extending through a first bone on one side of a skeletal joint and into a second bone on the other side of said skeletal joint, said rack assembly comprising: an L-shaped member having a base portion and an arm portion extending transversely of said base portion; a cannulated sleeve for movement through the bone tunnel in said first bone and into the bone tunnel in said second bone, said cannulated sleeve having a head portion at a free end thereof for disposition in the bone tunnel in said second bone and being connectable to the base portion of the L-shaped member at an opposite end, said head defining a window therethrough oriented substantially parallel to the base portion of the L-shaped member when said cannulated sleeve is connected to said base portion thereof, and said head extending beyond said window toward said free end so as to surround said window in a plane orthogonal to said window; a trocar sleeve guide member removably connectable to said arm portion of the L-shaped member and having bores extending therethrough at an angle normal to a projection of the longitudinal axis of said cannulated sleeve; first and second trocar sleeves for movable disposition in the bores, respectively; at least one trocar for disposition in said trocar sleeves, the trocar being interconnectable with said trocar sleeve in which the trocar is disposed, said trocar sleeve and said trocar therein being movable axially toward said head portion of said cannulated sleeve and rotatable together such that said interconnected trocar and trocar sleeve are adapted for drilling into the second bone and said at least one trocar is adapted to penetrate through the window in said head of said cannulated sleeve and a portion of a piece of tissue subsequently substituted therefore; said trocar being removable from said trocar sleeves; and said trocar sleeves being adapted to receive rods slidable through the trocar sleeves and through the portion of a piece of tissue, said trocar sleeves being removable from the second bone and from the rods so as to leave the rods in the portion of a piece of tissue and the second bone; wherein said head is configured so that when said head engages an end of the bone tunnel in said second bone, said window is aligned with said at least one trocar adapted to penetrate therethrough. 2. A rack assembly according to claim 1 wherein said trocar sleeve guide member includes separable first and second parts. 3. A rack assembly according to claim 1 further comprising said rods. 4.

An implement for manipulating and cutting a knotted suture includes a body member having a handle at one end, and a knot-engageable section at the opposite end for engaging the knotted suture to be cut; and a cutting member carried by the body member and having an end portion formed with a cutting edge for cutting the knotted suture at a predetermined distance from the knot. The cutting member is movable along its longitudinal axis from a normal position to an actuated position for cutting the knotted suture. The knot-engageable section of the body member is formed with an axial bore for receiving the end portion of the cutting member when the cutting member is moved to its actuated position, and with an angled bore intersecting the axial bore at an angle to the longitudinal axis for receiving the knotted suture. The knot is located at one side of the angled bore and the suture to be cut extends through the angled bore to the opposite side, such as to permit hand-tensioning the knot and then cutting the suture by moving the cutting member to its actuated position.

A method for fixing a portion of a piece of tissue in a bone tunnel comprising the steps of placing the portion of a piece of tissue in the bone tunnel, advancing spaced-apart first and second metal wires though the bone, transversely of the bone tunnel, so as to intersect the bone tunnel and extend into the portion of a piece of tissue, removing one of the wires and replacing the one removed wire with a first rod, and removing the other of the wires and replacing the other removed wire with a second rod, whereby to retain the portion of a piece of tissue in the bone tunnel with the rods.
